OHIO, ASSIGNOR TO TRUSCON STEEL COM- .A CORPORATION OF MICHIGAN WINDOW STRUCTURE Application filed April 4,

The present invention relates more particularly to window structures of metal, the object being to provide a very simple and effective actuating means whereby a plurality of sashes may be moved to different positions simultaneously and there left, and in which one of the sashes constitutes the main actuator for the others, the mechanism being such furthermore that the actuating sash maybe moved relatively to and independently of the others.

In the accompanying drawings:

Figure 1 is a vertical sectional View of a multiple sash window of the ventilator type,

5 showing three sashes and with all three in open position.

Figure 2 is a view similar to Figure 1, but with the lower sash closed.

Figure 3 is a detail perspective view of portions of the lower and second sash in order to illustrate more clearly the details of the operating mechanisms.

Figure 4 is a vertical sectional view on an enlarged scale through the lower sash and lower portion of the sash above it, showing both in closed position.

Figure 5 is a sectional view on the line 5-5 of Figure 4.

Figure 6 is a sectional view substantially line 66 of Figure 3.

Figure 7 is a sectional view on the line 7-7 of Figure 6. I

Figure 8 is a horizontal sectional view through one side of the frame and one sash,

showing the link mounting in top plan.

In the embodiment disclosed a window frame is employed, comprising side members 9 connected by a. plurality of cross bars 10. The side members 9 include inwardly set channel bars 11 backed by angle bars- 12. The outer flange 13 of each channel bar 11 is preferably wider than the inner flange 14. The cross bars 10 are preferably T-bars.

A plurality of window sashes are shown,

the two upper sashes being designated 15 and the lower sash carrying the reference numeral 16. This lower sash 16 is the actuating sash. Each sash frame is of rectangular form and is constructed of channel bars. The upper rail has its outer flange 17 shorter than 1929. Serial No. 352,478.

its inner flange 18, while the side bars and lower rail have their outer flanges 19 longer than their inner flanges 20. The consequence is that the said flanges will properlyoverlie the members of the window frame to proper- 1v shed moisture and prevent it driving past them.

Links 21 are pivoted at their lower ends to brackets 22 on the cross bars of the window frame, and have their upper ends pivoted, as indicated at 23 to the side bars of the sashes. These links therefore constitute supports and bearings on which the sashes swing and furthermore are so constructed that they lie within the window frame parallel to the sashes when said sashes are in closed position in the frame.

In the channels of the vertical side bars 11 of the window frame are located actuating bars 24 that are mounted to vertically. reciprocate. On these bars are fixed outstanding brackets 25 that are bent about the outer flanges 13 of the side bars 11 and project outside the window frame. .As shown particularly in Figure 7, the brackets 25 are vertically adjustable on the actuating bars 24 and to this end they are provided with vertical slots 26 through which are passed holding screws 27 threaded into the bars 24. Beneath the brackets and abutting them are adjusting screws 28 threaded through lugs 29 carried by the bars. By loosening the screws 27 and \turning the screw 28, obviously the brackets 25 can be'vertically adjusted on the bars 24 and by tightening the screws 27, said brackets can be firmly fixed to the said actuating bars. Fixed to the vertical side members of the two upper sashes 15 are brackets 30 that lie alongside the brackets 25 and are pivotally connected thereto at their outer ends as shown at 31. \Vith the structure as thus far de -,scribed, it will be evident therefore that if the bars 24 are moved in one direction, the upper sashes 15 will. be caused to swing outwardly to a more or less inclined position as illustrated in Figures 1 and 2, and actuating bars 24 are raised, the sashes will swing to their closed positions in the window frame.

The movement of the bars 24 is secured by when the i means of the lower sash 16. This sash is provided on its lower rail with a suitable actuating handle 32 pivoted to the rail and having a latch hook 33 adapted to engagebver a retainer 34 to hold the sash 16 in its closed position. This sash 16, asalready explained, is pivotally mounted on the links 21, and it is provided on its upper rail with means for detachably engaging with the actuating bars 24. This means is more particularly shown in Figures 4 and 5. On the upper corners of the lower sash 16 are mounted brackets 35, in which reciprocate bolts 36, and these bolts are adapted to engage in openings 37 formed in the actuating bars 24. The bolts are backed by springs 38 that serve to urge them toward the bars 24 and into the openings 37. The bolts are connected by links 39 to opposite sides of a crank disk 40 carried by a shaft 41 journaled in a housing 42 mounted on the upper rail of the sash. The shaft 41 is provided with an interposed operating handle 43. It will be noted by reference to Figure 5 that the bolts 36 pass through channeled sliders 44 that embrace and are adapted to slide on the actuating bars 24.

Assuming the bolts 36 engaged with the actuating bars 24 and all three sashes in closed positions, the latch 33 serves to lock all of the sashes. If now the handle 32 is raised, the latch 33 will disengage from the keeper 34 and the lower sash can be pushed outwardly. When thus moved, its upper end will move downwardly and the bolts 36 being engaged in the openings 37 of the actuating bars, said bars will correspondingly be moved. This draws down the brackets 25 and 30, thereby causing outward movements of the upper sashes 15. Because of the structure shown and the proportions of the parts, the sashes will remain wherever left. If it is desired to close the lower sash after the upper sashes are opened, it is only necessary to turn the handle 43, whereupon the bolts 36 will be disengaged from the actuating bars 24 and the sash 16 can be drawn to closed position leaving the upper sashes opened as desir In this actlon it will be noted that the bolts 36, though freed from the bars 24, will remain in engagement with the sliders 44, so that the necessary guiding action for the upper end of the lower sash is maintained. It will also be clear that if it is desired to open the lower sash, leaving the upper sashes closed, this can also be accomplished by disengaging the bolts 36 from the actuating bars 24 and moving the lower sash alone.

From the foregoing it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description and it will be understood that various changes in the size, shape, proortion and minor details of construction may e resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What I claim, is:
